Originally, Nemty appears to have been the patron of the ancient area around Badari, which was the center of the cult of Horus.

His later cult center was in Antaeopolis, but also in Per-Nemty (House of Nemty) in the 12th Upper Egyptian nome.

In this tale, one of Seth's attempts to gain power consists of his gathering together the gods and providing good arguments, convincing all of them (in later traditions, all except Thoth).

However, Isis disguises herself as an old woman and unknowingly Nemty takes her across after being paid a gold ring, having rejected the first offer of gruel, resulting in the disruption of the council by her use of magic.

Nemty is punished for his error, by having his toes cut off, which is more severe than it appears, since as a falcon, he would no longer be able to perch and thus would not be able to reside on the boat.
